NotebookLM has been on a roll lately. Just last week, Google rolled out a bunch of improvements and new features to the tool. While some of the updates are relatively minor, two features are designed to take on tools like PowerPoint and could really change how you use the platform: Infographics and Slide Decks.

Both are powered by Nano Banana Pro, and while they haven't been around for long, a quick glance at Reddit, the NotebookLM Discord, and social media shows just how well-received they are. Unfortunately, the excitement seems to have been cut short.

NotebookLM rolls back slide decks and infographics temporarily

As announced via a post on X (formerly Twitter), NotebookLM has temporarily rolled back access to Slide Decks and Infographics for free users. For paying users, additional usage limits have been added. In the post, Google cited “overwhelming demand” as the reason, explaining that the surge in usage has created capacity issues that need to be addressed before the features can return to normal.

At the time of writing, it’s unclear what the limits for Infographics or Slide Decks actually are, since none of the support articles seem to clearly define them. For instance, here's what is mentioned in the "Upgrade NotebookLM" support article, which outlines the limits for other features:

With NotebookLM, you get 100 notebooks, each with up to 50 sources (up to 500K words each), and daily limits of 50 chat queries. You can generate deep research searches 10 times a month. For artifacts, you can generate up to: 3 audio generations, 3 video generations, 10 reports, 10 quizzes, and 10 flashcards. Infographics and slide decks are also available, subject to daily limits.

While it clearly defines limits for other features, it offers no real clarity on how Infographics or Slide Decks are capped. The same is true for Pro users. The support article lays out the upgraded limits for Pro users, but still doesn’t mention any specific numbers for Infographics or Slide Decks. I’ve reached out to Google for more details on the specific limits and will update this story once I hear back.

The post doesn’t mention a timeline for full access to return. For context, Slide Decks let you turn your notes into visually structured presentations, while Infographics transform key information from your notes into visually engaging summaries. Both features rely solely on information from sources you’ve uploaded to your notebook and are customizable. All that said, I have my fingers crossed that Google will resolve the capacity issues soon and restore full access!
